To all whom it muy concern:

Be it known' that I, EDWINKW. WEBB, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented certain new and use'-y ful Improvements 1n Side Bearings andl Supporting-Arches forl Car-Trucks; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art. to which, itzfappertains to make and use the same.

My invention p. relates to six-wheeled car trucks and is directed to the provision of an improved side bearing arch and side bear-.p

ing for trucksofthis character.

Generally stated, the inventionconsists of the novel devices and combinations of devices hereinafter describedand defined in the claims.

ln the accompanying drawings which" illustrate the invention, like characters in# dicate like `partsthroughout theiseveral views.

Referring toothepdrawings: Figure 1 is a' plan view showing a six-wheeled car truck, some parts being broken away;Fig;y 2 is a" side elevationl of the parts shown ink Fig. l

Fig. 3 isv an enlargedy elevation with 'some parts sectioned, showing the central portion of one of the side bearing archesland one of the improved side bearings applied theref to; and Fig. t is a vertical sectiomthe right` y end portion thereof being in `section on `the line r4-m4, and the left end part beingsecf` tioned on the line y-y on Fig. 8; op

Of the parts of the truck, the numeral l indicates the wheels,`2 the axles, 3 the truck frame, 4 the equalizers, and 5. the springsupported truck holsters, yall of which parts are, or may be assumed to be of standard well known construction.

lThe side bearing varch bars l6 are cast structures (preferably cast steel) and vat their central portions, they are widened `and formed with pockets or mortises `7,. (preferably open in the bottom so that dust, dirt or water cannot accumulate 'f within the same), to receive the side bearing rollers 8. These side bearing rollers are preferably arranged in pairs, that is, two foreach arch barand they are journaled on pins9 passed through holes in the side walls of the pocket *n 7. rlhe rollers are set so that their upper portions project considerably vabove the .up-y per surfaces of the arch bars'. V

' Coverl plates l0 which have openings through which the upper portions of the rollers project, are seated on the tops ofthe arch bars and close the tops of the pockets 7, and they are provided with down-turned side flanges that overlap more or less, the ends of the pins 9, and thus serve to hold the said pins against endwise or axial displacement. The cover plates themselves are heldin position by nutsequipped bolts 11 passed through the central portions of the side flanges thereof, and through the walls of the pockets 7 midway between thetwo rollers. rihe cover plates above described are preferably made of malleable iron, but may be made of pressed steelV or otherwise formed. V f l 'The ends of the arch bars 6 rest upon the ends of the truck bolster 5, and .arerigidly Een.

secured thereto by bolts or other suitable de 'j vices; and when theyzare thus applied, the sidebearings'are supported in proper position fori engagement with the customary cooperatingbearing plates on the car body.

VllVhatIclaim is:

l. ln a six-wheeled car truck, side bearing arch barsjprovided at their intermediate' portions with pockets and with side bearing rollers journaled in said pockets.

yEZ. In a six-wheeled car truck, sidebearing arch bars provided at their intermediate portions with pockets and with side bearing rollers journaled in said pockets, the said pockets ,having open bottoms.

3. Aside bearing arch, bar for cartrucks, provided at its intermediate portion with a pocket, and with rollers journaled Vin said pocket.

4f. A side bearing arch bar for car trucks,

yprovided at its intermediate portion with a pocket, `and with rollers journaled in said pockets, the bottom of said pockets being open.

5. A cast side bearing arch bar for six" \wheeled trucks formed at its intermediate portion with a pocket, a pin extended through said pocket and the walls thereof, rollers Vjournaled on said pin and a cover plate secured to saidbar and having de-j pending flanges overlapping theV ends of said pin and holding the same against end-` wise displacement,
